**PICKUP SYDNEY PRICE ** We can help with freight quote, this is pick up price **
Water-cooled induction forge that runs on a 60A 240 V circuit and heats up steel in seconds to a max of 2200 C.
Small unit for single blades and bars of steel when forging.
- Easy to use induction forge with coil about 45 x 60 mm
- Runs on 240 Volt, single phase power circuit
- Two heating coils included
- One foot pedal included for ease of operation
- hose clamps, replacement fuses included
- Requires 750 W water pump ($129 at Bunnings Apr 2024), 200 liter cooling water container and 1/2" hoses that are not included
Please note carefully:
- Water pump: The induction forge requires to be water-cooled to not be damaged in use. This can be done using a cooled tank system, like a TIG welder cooler or a cooling system with radiator, or a much bigger water body if not having a radiator/cooler on the system. Minimum 200 liters for light use on the 15 or 25KW systems.
- RECOMMENDED PUMP is the 750 W Ryobi dirty/clean water pump from Bunnings - note a small pond pump has enough liters/minute but not enough power to run the induction heater. As on April 2024 this is $129 from bunnings.
- The pump has to have minimum 7 liters per minute and the cooling water needs to stay under 40 C at all times. Note a small pond pump will list capacity as much more than 7 liters per minute but does not deliver enough pressure and will not work.
- Cooling water: Hard water can damage the induction forge by calcifying the inside of the coil and other parts of the cooling system. The safest coolant is distilled water as this has had the minerals removed, including any calcium. In Sydney the water is considered quite soft and you may be ok to use this but the safest bet is destilled water. Woolworths sell distilled water for about $1 per liter. Using a too small tank will make the induction forge stop until the water is cold enough again.
- Note the need for destilled or very soft water to avoid calcium build-up inside the coil, and clean water or a sealed system where dust and other things cannot get into the water to contaminate it.
- Keep the cooling water running at all times while the induction forge is powered on, and check the temperature of the coolant water regularly.
- Electrician required: power plug needs to be fitted to the already attached power lead, and 60A or larger capacity circuit is recommended. The induction forge should be grounded for operator safety.
- The heating coil comes with insulation for transport, spray with some high-heat paint for longer-life when the insulation falls off after some use. The coils need a layer of insulating paint, exchaust putty or similar to stop the copper coil shorting on the steel held inside the coil, should they by accident touch.
- Coils can be made from copper tubing, for custom jobs. For instance a more rectangular coil for wide bar stock, or a small diameter, longer coil for heating longer sections of smaller diameter rod, etc.
- The main issue with these over time is the cooling water not being soft enough (not using destilled or really soft water), or having an open container where dust and other items can fall into the water tank. A closed cooling system with destilled water or really soft water will be required to ensure several years of operation.
Manufactured in China, these are an introduction-level induction forge with both coil, cooling and electronic controls in one box.
Weight of unit is about 24 kg, 50 x 45 x 20 cm plus coil that screws to the front and the water hoses that attach with hoseclamps to the back of the unit. There is one water intake and 3 x water out.
The 15KW is not the actual power usage but the calculated "Instantaneous output power 15KVA" at the coil. The power usage is closer to 8 KW. This is why the circuit required is about 36A with a 60A breaker.

Nice addition to the workshop
I am a sucker for technology stuff, so when I found out about the induction forge imported by Nordic Edge naturally I am interested to acquire the machine. After a few weeks of soul searching and finding a way to justify the purchase (from SWMBO), I contacted Bjorn to get one of these. The purchase process: This is absolutely flawless as is the norm with this supplier, and the delivery was definitely personal - Thank you Nordic Chris :) On installation: I found out that the forge requires high-pressure water system to cool the coil and the internal components of the machine, a standard pond pump is not suitable for it. On recommendation from Bjorn and Karim from Tharwa Forge, I bought a submersible 750 watts Ryobi pump, this works well with the machine. For the cooling wter container, I use 40 liters Sistema plastic storage with lid - and with some holes drilled on the lid for the hoses and electrical cable for the pump. My impression of the machine: If you wish to do some blacksmithing, this machine is a very good addition to the workshop. The machine can heat up a piece of steel within seconds - this would increase production time greatly. If you need to bring it high enough to welding temperature, simply heat it up a bit longer and it would get to the required heat or beyond. This is an awesome tool if you wish to quickly heat up and shape a piece of metal. I do not do much blacksmithing, my need for a forge is mainly to heat treat the stamps I made, and thus I would need to find a way to control the required temperature and holding time for the steel I use, this would be an interesting exercise for the future. I would also explore the possibility of this machine melting some metal (brass, aluminum, or such) to cast in the future with the correct crucible that fits the coil (or make a coil that fits) Would I recommend this machine to others? Unreservedly YES.

15kW Induction Forge
Once connected up and plumbed in it worked as expected. Heats up fast and easy to use. If there is one criticism I could have it would be that it came with two of the same coils and they were in the wrong orientation for me. They were vertical as opposed to horizontal. Fixable but for forging I would suspect it would be the norm to have them horizontal. Apart from that so far, so good.
